<p>These options are defined specifically for the CR16 ports.
</p>
<dl compact="compact">
<dt><code>-mmac</code></dt>
<dd><a name="index-mmac"></a>
<p>Enable the use of multiply-accumulate instructions. Disabled by default.
</p>
</dd>
<dt><code>-mcr16cplus</code></dt>
<dt><code>-mcr16c</code></dt>
<dd><a name="index-mcr16cplus"></a>
<a name="index-mcr16c"></a>
<p>Generate code for CR16C or CR16C+ architecture. CR16C+ architecture 
is default.
</p>
</dd>
<dt><code>-msim</code></dt>
<dd><a name="index-msim-2"></a>
<p>Links the library libsim.a which is in compatible with simulator. Applicable
to ELF compiler only.
</p>
</dd>
<dt><code>-mint32</code></dt>
<dd><a name="index-mint32"></a>
<p>Choose integer type as 32-bit wide.
</p>
</dd>
<dt><code>-mbit-ops</code></dt>
<dd><a name="index-mbit_002dops"></a>
<p>Generates <code>sbit</code>/<code>cbit</code> instructions for bit manipulations.
</p>
</dd>
<dt><code>-mdata-model=<var>model</var></code></dt>
<dd><a name="index-mdata_002dmodel"></a>
<p>Choose a data model. The choices for <var>model</var> are &lsquo;<samp>near</samp>&rsquo;,
&lsquo;<samp>far</samp>&rsquo; or &lsquo;<samp>medium</samp>&rsquo;. &lsquo;<samp>medium</samp>&rsquo; is default.
However, &lsquo;<samp>far</samp>&rsquo; is not valid with <samp>-mcr16c</samp>, as the
CR16C architecture does not support the far data model.
